Abstract
For an infinite number of transmit antennas at a base station (BS), matched filter (MF) precoding (a type of precoding used to perform SU-MIMO transmission) becomes optimal for performing spatial multiplexing. But observations have shown that precoding types for performing MU-MIMO transmission can perform significantly better than MF precoding for a realizable number of transmit antennas at the BS, even while using the simplest precoding types for MU-MIMO transmission. For large inter-cell interference typically encountered by user terminals (UTs) at or near the boundary of the cell served by the BS, MF precoding can still be used to eliminate or reduce the need for coordination among cells, which consumes network and back-haul resources.
